Abstract
A pressure bulkhead has a plurality of holes and divides a low-pressure chamber at low pressure in the vertical direction. A cooling-tube bank is located in an upper section of the low-pressure chamber and performs heat exchange with low-pressure steam guided to the low-pressure chamber by introducing coolant therein to condense the low-pressure steam to low-pressure steam condensate. A reheat chamber serves as a lower section of the low-pressure chamber and stores the low-pressure steam condensate falling from the holes in the pressure bulkhead. A high-pressure-steam introducing unit introduces high-pressure steam within a high-pressure chamber at high pressure to the reheat chamber. A plurality of plate members are parallel to each other below the pressure bulkhead and extend in a falling direction of the condensate falling from the holes in the pressure bulkhead.
